Transatlantic telephone cables were broken in the Grand Banks earthquake in 1929. The [transatlantic telephone cable] article says the first telephone cable was laid in 1956. Was it telegraph cables that were broken in 1929?63.78.97.2 (talk) 16:43, 6 February 2008 (UTC)[reply]

Speed of sound

The fourth paragraph of the introduction says "Turbidity currents can reach speeds up to half the speed of sound". Does this refer to the speed of sound in the air or in water? — Preceding unsigned comment added by 50.21.142.18 (talk) 01:22, 8 October 2013 (UTC)[reply]

Undersea river?

I mentioned on the talk page of a new article, Undersea river, that "undersea river" seemed to be a colloquial term for "turbidity current". Its BBC source seems to maybe use the terms interchangeably, but then I read "Cryptic River"^[1] and now I'm wondering if "undersea river" is a subtype of "turbidity current"? I'm hoping that editors watching this page with more expertise than me can help out here. Could "undersea river" be addressed in this article (and the new one be a redirect here) or are these concepts distinct enough that they should be separate articles? I couldn't find a source that directly addressed the relationship between the two terms, at least not in a way that I understood. (This is so not my area of expertise.)

Pinging @GeoWriter, Jayzlimno, and Licks-rocks: as possibly being able to weigh in on this question (names from history of this article and Wikipedia:WikiProject Limnology and Oceanography). Schazjmd (talk) 18:14, 9 December 2024 (UTC)[reply]
- I'm not an oceanographer but do study lakes and rivers. From what I can gather, "undersea river" is a more colloquial term for a type of Gravity current occurring in the oceans that mimic some (on-land) river properties. "Turbidity currents" are a type of gravity current and probably the most commonly-described type of gravity current mimicking rivers in the oceans, although density differences resulting from differences in temperature or salinity can produce substantial flows including underwater features that look like "waterfalls" or "rivers"; e.g., Denmark Strait overflow or Black Sea undersea river. I would caution against calling these "rivers" or "waterfalls" because they are fundamentally different things - although describing them this way does help us (the public) visualize what's happening under the oceans. Refer to this article ^[2] that uses "river" in title but goes into detail on how submarine channels are formed by turbidity currents - there is also a nice section (subtitle "The river analogy") in this article describing the differences between deep-sea channels and river systems. I'd recommend that the "undersea river" article redirects to "turbidity current" as that seems to be the most commonly-described type of "undersea river", although other types of flows stemming from density differences do occur, e.g., Black Sea undersea river.

  - Thanks for the input, Jayzlimno (talk · contribs). I hesitate to redirect without any mention of "undersea river" in the "turbidity current" article. Is there an accurate and appropriate way to introduce that term into this article? Schazjmd (talk) 17:57, 11 December 2024 (UTC)[reply]
    - I agree that "undersea river" seems to be a colloquial term for turbidity current and I also agree that the undersea river article should be changed to a redirect to the turbidity current article. GeoWriter (talk) 20:42, 11 December 2024 (UTC)[reply]
    - Maybe introduce it in the first paragraph of the "turbidity current" article? I don't think it needs to be extensive explanation though, could be something like, "Turbidity currents are sometimes referred to as 'undersea rivers', although there are fundamental differences between rivers and turbidity currents."
